[This review was collected as part of a promotion.] I purchased this speaker a few weeks ago and really happy that I did. The sound quality is really good and the build quality is fantastic Feels rugged and solid. It is only 5w but this shouldn't put you off. The sound is rich and the added portability is a bonus. The device is also water and dust resistant, and quickly connects to my mobile. Packaging is made from carefully sourced materials. Right down to the cable ties. Only quibble is the size of the writing on the instruction leaflet, it could do with being in a larger font.but apart from that, I would recommend this product to anyone in the market for a portable Bluetooth speaker
